Does Kay LiDE mobile navigation charge for software?

the software is large, about 1.2G! So basically you don't need to connect to the internet after downloading! So 5 yuan monthly subscription is enough! Explain it in detail! Kay LiDE navigation software is quite good, except for voice navigation, which is free every time in 2 yuan! Of course, we generally don't need to use its voice navigation! It's just an electronic dog! If you don't start this function, the rest is free navigation!
